Improvements and fixes
  • Translates some terms for multiple languages to make sure the accuracy of the meaning.
  • Fixes the following issues:
    • When you send an email message that contains a meeting information to a SIP address in Microsoft OneNote 2013 (for example, using the Email Page function or the Share with Meeting function), the email message is undeliverable. This issue occurs if Microsoft Lync 2013 (Microsoft Skype for Business) is not installed and the SIP address differs from the SMTP address.

      Note To resolve this issue, see Email that contains meeting information is undeliverable when you send it to a SIP address in OneNote 2013 (KB3055026).
    • When you try to search a people by using the Search People box in Microsoft Outlook 2013, Outlook 2013 crashes.
    • When enterprise customers open an Office 2013 application on a computer that is configured to use basic authentication, they might be prompted for credentials.
